Why customers love it

Seal out water and corrosion in one quick heat step

These solder seal wire connectors combine a pre-formed solder ring, heat-shrink tubing, and hot-melt adhesive so you can splice and insulate wires in a single step. The result is a strong, watertight connection built to handle vibration and harsh environments.

  • One-step installation: heat to melt the solder and shrink the tubing simultaneously
  • Waterproof and insulated seal with built-in hot-melt adhesive lining
  • Tin-plated copper terminals ensure excellent conductivity and corrosion resistance
  • Durable polyolefin outer tubing provides strain relief and cable protection
  • Operating temperature range from -55°C to 125°C for versatile use

Why choose these solder seal connectors

Waterproof seal

The built-in hot-melt adhesive lining creates a watertight, insulated seal that protects against moisture and corrosion.

Reliable conductivity

Tin-plated copper terminals ensure excellent conductivity and corrosion resistance for dependable connections.

Cable protection

Durable polyolefin outer tubing provides strain relief and cable protection, helping the connection hold up under vibration.

Wide temperature range

Rated for operating temperatures from -55°C to 125°C, these connectors suit a broad range of environments.

Setup

How it works

No electrician, no wiring, no fuss.

  1. Position the connector

    Slide the connector over the wire joint, centering the solder ring over the splice.

  2. Apply heat

    Heat the connector until the solder melts and the tubing shrinks tightly around the wire.

  3. Done

    The solder and adhesive flow together to create a waterproof, insulated seal in one step.
